Apparatus, system and method for an air bearing stage for component or devices
The disclosure provides an apparatus, system and method for a moveable bearing stage that allows for highly refined alignment and placement, and particularly planar alignment and placement, of component or devices through the use of robotics. The apparatus, system and method of providing at least a planar alignment of at least one component or device in relation to a secondary reference plane may include at least: a frame and stator assembly, having, at an upper portion thereof, at least a semi-spherical receiving interface; a movable assembly that moves within the frame and stator assembly, and that is connectively associated therewith by at least a plurality of springs; a semi-spherical stage, suitable for reception by the semi-spherical receiving interface and capable of at least rotational movement therewithin; a chuck within the semi-spherical stage and capable of at least co-planar, post-planar, and ante-planar positioning in relation to a plane provided by a topmost portion of the semispherical stage, wherein the chuck is capable of receiving the component or device; and at least two gripper jaws suitable for receiving and holding, at an upper portion thereof, the component or device, wherein the two gripper jaws comprise, at a lower portion thereof, at least ramps capable of physically interacting with ones of the motion stops.
1. An alignment system for providing at least a planar alignment of at least one component in relation to a reference plane, comprising:
a frame and stator assembly;
a movable assembly having spring limited motion within the frame and stator assembly, comprising:
a floating yoke portion floating on an air stage and having associated therewith a tactile portion that is suitable for assessing a plane of a topmost portion of the component in relation to the reference plane;
a semi-spherical stage capable of at least rotational movement;
a chuck within the semi-spherical stage that is capable of at least co-planar, post-planar, and ante-planar positioning in relation to a stage plane provided by a topmost portion of the semispherical stage; and
at least two synchronized gripper jaws associated with the chuck and being suitable for receiving and holding, at an upper portion thereof, the component, wherein the two gripper jaws comprise, at a lower portion thereof, at least two ramps capable of physically interacting with ones of the motion stops to center the chuck;
wherein the movable assembly places a plane provided by the topmost portion of the component into a processing position with respect to the reference plane so as to allow for processing of the component and a second electronic element.
2. The system of claim 1 , wherein the floating yoke stage comprises movement with at least +/−6 degrees of rotational freedom.
3. The system of claim 1 , further comprising a vacuum actuated to hold the component during gripping by the two gripper jaws.
4. The system of claim 1 , wherein the tactile portion further comprises at least high precision compounded x,y,z, theta powered stages.
5. The system of claim 1 further comprising a travel sensor for sensing at least z-axis travel of the yoke.
